Hello Igor,
Thanks for your reply.
I took a look in the Datasheet and the application note, to find that we can test the Transceiver if it still working correctly or not by putting one of the Loop back mode, as shown in screenshot, in my case I need to test the external loop back mode
But there is no mention, what should I do after I put the Trcv in that mode
shall I send a message and then listen on the receive side till I got a reception and compare between the sent and the received one
and check if they are the same.
or what?
Hi Ahmed
you are right, send, receive and compare.
Best regards
igor
Hi Ahmed
for diagnosis one can try loopback mode described in
